| Inhoud: |
Seedlings of Fe-efficient tomato plants were cultured in nutrient solutions with two concentrations of Fe and K. The pH of the nutrient solution increased initially in all treatments. A subsequent drop in pH of the nutrient solution to 4.4 occurred only in the low Fe, normal K treatment. Ferric iron reduction by root samples was markedly increased only in those producing a decrease in pH of nutrient solution. Most “Fe-reductant” was released from the swollen elongation zones of young roots. Chlorophyll content in young leaves (after a pH Fe-stress response) was greater with normal K versus low K for both normal and low iron treatments. Iron-stressed plants accumulated more K/g dry weight, especially in the roots, than with normal Fe supply. |
